FLUSH-TANK FIXTURE.

Application filed February 3, 1922.

To all whom it may concern:

Be it known that I, ALFRED A. Emacs, a citizen of the United States, and a resident of New York, county of Bronx, and State of New York, United States of America, have invented certain new and useful Improvements in Flush-Tank Fixtures, of which the following is a specification.

This invention relates to flush tank fix tures and particularly to the valve mechanism of such fixtures.

One of the objects of the invention is to provide a tank fixture of the character de scribed that is simple in construction, coinprises few parts and may be economically manufactured.

Another object of the invention is to provide a fixture that is positive and quiet in operation and in which the parts are so constructed and arranged that they will not be thrown out of adjustment in use.

Another object of the invention is to provide a construction that is rugged and will operate effectively and quietly without the use of packings, washers or similar devices.

Further objects of the invention will appear from the following specification taken in connection with the drawings which form a part of this application and in which Fig. l is a sectional elevation of a flush tank having a fixture constructed in accord ance with the invention mounted therein, this view being taken substantially on line 11 of Fig. 2.

Fig. 2 is a top plan view of the construction shown in Fig. 1.

Fig. 3 is a sectional elevation taken through a portion of the valve mechanism and showing one of the valves in open position and Fig. 4 is a sectional elevation of the valve mechanism taken substantially on line 4.4 of Fig. 2.

The invention may be briefly described as comprising a fixture mounted in a flush tank and having'a U-shaped flush or out-let pipeof the usual construction and a casing mounted in the tank and, in the particular embodiment shown, secured to the outlet pipe. The ca-singis divided into two vertical sections. the upper section forming the supply chamber having a water inlet and the lower section being subdivided into two chambers, eachhaving awater outlet, one

leading to the tank and the other leading to the outlet leg of the U-shaped flush pipe. The connection to the flush pipe is so con structed and arranged that a conical spray will be introduced into the outlet leg of the pipe. A pair of valves is provided for con trolling the ports between the upper chamber and the two outlet chambers and one of these valves is manually controlled. and the other valve is controlled by the water level in the tank. The heads of the valves are conical and seat in conical seats, no packings being used. Further details of the invention will be explained in the following description.

In the drawings, 1 have shown a flush tank 10, having secured thereto a U-shaped siphon or flush pipe having its inlet leg 11 disposed adjacent the bottom of the tank and having its outlet leg 12 extending through the bottom of the tank and secured thereto.

The leg 12 of the outlet or flush pipe is interrupted at 13 and a casing 14. is secured to this portion of the leg 12.

The casing 14 comprises an upper chamber 15 and a pair of lower chambers 16 and 16*, the chamber 15 and chambers 16 and 16 being connected by ports 17 and 17 having conical seats. A water inlet pipe 18 is secured to the casing and communicates with the upper chamber 15 and a water outlet pipe or feed pipe 19 for the tank is secured to the casing and communicates with the lower chamber 16 and as shown in Fig. 1 this pipe extends to a point adjacent the bottom of the tank whereby the water fed through this pipe to the tank will stir up any residue or dirt at the bottom of the tank and will tend to keep the tank free from such matter.

As shown particularly in Figs. 3 and 4, the casing has formed on its lower section a pair of downwardly extending sleeves 20, the lower ends of these sleeves being closed by plugs 21. having restricted openings 22 therein. In each of the sleeves 2O is positioned a valve stem 23 of a valve having a conical head 24 adapted to seat in one of the ports 17 connecting the upper and lowerchambers of the casing. Each valve stem is provided with a plurality of grooves 25 forming water seals.

One of the valves has its stem engaged by an end 26 of a bell crank lever, the otherill with a pair of chambers, ports between the single chamber and the pair of chambers, a pair of valves controlling said ports, an inlet pipe leading to said single chamber, outlet ports in said other chambers leading to the outlet pipe and to the tank, manually controlled means for actuating one of said valves and means controlled by the water level in the tank for controlling the other valve.

3. In a flush tank fixture, a tank, an unobstructed U-shaped outlet pipe having one leg adjacent the bottom of the tank and the other leg extending through the bottom of the tank and means surrounding the pipe for directing a converging spray under pressure from outside of the pipe into the outlet pipe at an unrestricted portion thereof.

In a flush tank fixture, a casing having a pair of sections arranged one above the other, ports connecting said sections, an inlet pipe secured to the upper section, downwardly seating valves for said ports, outlet ports in the lower section, manually operable means for raising one of said valves and means controlled by the water level in the tank for raising the other valve, said valves being closed by the pressure of the water in said upper section of the casing.

In a flush tank fixture, a casing having an inlet chamber, and a pair of outlet chambers, the inlet chamber and outlet chambers being arranged one above the other, ports having conical seats connecting said inlet and outlet chambers, an inlet pipe secured to the upper chamber, downwardly seating conical valves for said ports, outlet ports in the lower chambers, manually operable means for raising one of said valves and means controlled by the water level in the tank for raising the other valve, said valves being closed by the pressure of the water in said upper section of the casing.

(5. In a flush tank fixture, a casing having a pair of sections arranged one above the other, the upper section having one chamber and lower section having a pair of chambers, ports connecting said upper chamber and lower chambers, an inlet pipe secured to the upper chamber, downwardly seating valves for said ports, outlet ports in the lower chambers, actuating means for raising said valves, said valves being closed by the pressure of the water in said upper section of the casing and hydraulic means for cushioning the closing movement of said valves.

7. In a flush tank fixture, a casing having a pair of sections arranged one above the other, the upper section having one chamber and lower section having a pair of chambers, ports connecting said upper and lower chambers, an inlet pipe secured to the upper chamber, downwardly seating valves for said ports, outlet ports in the lower chambers, actuating means for raising said valves, said valves being closed by the pressure of the water in said upper section of the casing, and hydraulic means controlled by the valve movement for cushioning the closing movement of said valves.

8. In a flush tank fixture, a casing having a pair of sections arranged one above the other, ports having conical seats and leading from the upper section to the lower section, an inlet pipe connected to the upper section, outlet pipes connected to the lower section, a pair of valves having conical heads adapted to seat in the ports, manually operable means for lifting one of said valves and means controlled by the water level in the tank for lifting the other valve, the valves being closed by the pressure of the water thereon.

9. In a flush tank fixture, a tank, a U- shaped outlet pipe therein having an inlet end disposed adjacent the bottom of the tank and an outlet leg extending through the wall of the tank, a casing, a water inlet pipe secured thereto, means for conducting a spray of water from the casing to the outlet leg of the Ushaped pipe and independent means for conducting water from the casing to said leg of the outlet pipe.

10. In a flush tank fixture, a tank, a flush pipe connected thereto, a casing having a pair of sections arranged one above the other and having a pair of ports establishing communication between said sections, a pair of sleeves formed on the casing and extending downwardly from the lower section, and upwardly opening valves for said ports having stems mounted in said sleeves and 0011- trol means for said valves.

'11. In a flush tank fixture, a tank, a flush Jipe connected thereto, a casing having a pair of sections, arranged one above the other and having a pair of ports establishing communication between said sections, a pair of sleeves formed on the casing and extending downwardly from the lower sec tion and having restricted openings in the lower ends thereof, and upwardly opening valves for said ports having stems mounted in said sleeves and control means for said valves.

12. In a flush tank fixture, a tank, a U shaped outlet pipe therein having an inlet end disposed adjacent the bottom of the tank and an outlet leg extending through the wall of the tank. a casing, a water inlet pipe secured thereto and an outlet nozzle on said casing connected to and surrounding the outlet leg of the U-shaped pipe and constructed and arranged to conduct a conical spray of water to said pipe from outside of the pipe at an unrestricted portion thereof.

13. In a flush tank fixture, a tank, a U- shaped outlet pipe therein having an inlet end disposed adjacent the bottom of the tank and an outlet leg extending through the Wall of the tank, a casing surrounding the outlet leg of the U-shaped pipe and connected thereto near the upper end 01, said leg at an unrestricted portion thereof, a water inlet pipe connected to the casing, said casing and pipe being constructed to form an outlet nozzle arranged to conduct a converging conical spray downwardly toward the longitudinal axis of the pipe.
